Bought this to carry my over 17inch laptop for business trips. So far I've used it for 2 and really don't like it. It does the job but not all that comfortable.

Pros- it holds my huge laptop- has a place I can plug in and charge stuff without looking around in the bag- may pockets to keep organized and ease of access when on the run- pockets to hold 2 water bottles- a strap that I can place over my suitcase extension handle- padded straps

Cons- bag is top heavy, my laptop is probably not helping, and wants to and does fall on it's face when it on my suitcase. I use the top strap to hold it from falling over- does not form fit to my back and there is a noticeable gap. This ends up giving me back mid back pains.- sunglass strap made me almost lose my sunglasses. If it was a bit more tighter I would use it again. In the meantime, never using it again.

I travel a lot for work and noticed that some bags come with a buckle above the chest and understand why with this bag.

Also if the strap that holds onto my suitcase was higher, I wouldn't have the top heavy issues that I have now.

In the meantime this is what I'll use till I upgrade my laptop and can justify another bag.

All the pics are from my last trip and I am very short, so don't think it's a huge bag. If you have a small lap top, this would probably have less issues than I have.

5 Stars because the quality is superb. It's a genuine shame that my laptop cannot fit in it because I genuinely loved the back pack itself. The Problem is that it doesn't actually fit a 17.3 inch laptop. The zippers will not seal without stretching beyond acceptable tolerances. So I am returning it for that reason. For any future buyers, if your laptop is bigger than 17 inches FLAT Do not buy this. It is advertised at a 17.3 inch laptop bag but it will not close properly

This bag is super durable, well made, and nice looking. The biggest perk of it is all the storage - it has one large laptop compartment (which actually fits a thin laptop and multiple notepads), then another main large compartment which I use for my lunch, water bottle, umbrella, and lots of other miscellaneous items. Then it also has a medium sized front pouch that fits my wallet, hair brush, etc., and a slim front pocket for keys, phone, headphones, etc. Two side pockets that are also great for a metro card, even can fit a water bottle in them.

That said, there are two drawbacks to this bag. One, it is HUGE. Like, way bigger than I'd ever need. This is my own fault for not measuring what I wanted better. That said, I'm a 5'8" female, and this bag goes from my tailbone to my neck, easily. It would fit a 6'2" male well, I think. But for me, it feels overwhelming. The size is the main reason the storage is so great, I guess, but I feel it could be 3-4 inches shorter and still have ample storage.

The second drawback is comfort. The back of this bag and underside of the straps are made of black mesh, similar to many other bags, but the mesh is SUPER rough and scratchy and hard. Perhaps once i break this bag in more, it will soften, but after 2 weeks it's still very scratchy and the straps are so wide that it rubs on my neck and shoulders (if i wear a sleeveless shirt) during my commute. Also, the bag is so big that it feels unbalanced and pulls on my back/shoulders, even when adjusted. Otherwise, the back and straps are cushy, so that helps with comfort.

Overall, I'd recommend this for anyone looking for a really big/high storage backpack, but definitely consider the size before purchasing.

Arrived sooner than expected and is very nice quality. I always worry about straps holding up with all the crap I carry around, and I’m not worried about this one at all. I love that the laptop compartment is padded on both sides and completely separate from the main compartment (unlike the thin sleeve that most computer bags feature). It is very spacious and computer compartment will fit a large laptop, but still has enough padding that a smaller and thinner MacBook won’t flop around either. It’s a good bag for sure and looks like it will hold up for years even with the most careless of folks.

This backpack is enormous, which is exactly why I purchased it. It fits my 17” laptop with ease and all of my folders and papers and other supplies that I need for work. Even though it’s pretty heavy by the time it’s loaded, the weight distribution is excellent and it rests easy on my shoulders without discomfort. I would highly recommend.

Clean. Chic. Holds a lot of books and my laptop. What I especially like is the padding on the back and on the straps that help take the strain off my back and shoulders. I carry my laptop to work and to class all day. I usually walk about 4 miles to work in the city and I've noticed a change in how tight my stride is with this backpack. It doesn't swing, it sits nicely on my shoulders; it's a must for busy graduate students or commuters who need a comfortable--but clean and modern looking--backpack.

I haven't used the USB charger. It seems cumbersome and unnecessary, but luckily the cable can be discreetly tucked away.

I love this backpack. Lots of pockets for everything. The drink pockets on the side come in handy. Sleek, stylish, looks great. Very happy with this purchase. The only minor issue was that the backpack was slightly dirty from some packaging residue, but it rubbed off very easily.

And I don't love the, or need, the USB adaptor. I guess it would come in handy if you're in the middle of nowhere and need to keep your phone charged with a battery -- but you still wouldn't need to feed it through your backpack, so it doesn't make a lot of sense to me. I considered deducting a star for this, but the cable stores away in a side pocket and doesn't really get in the way.

Good quality, spacious. Perfect for a teacher that is always on the move. Enough pockets to accommodate everything. Not 5 stars because is missing one of the zippers leather strap. So I can not open the side pocket. Contacting Amazon now.

I love this bag. My bulky 17 inch gaming PC fits perfectly. There are so many other compartments I'm yet to fully utilize. It says a lot about the amount of space in this thing. I will be using it for all my hand baggage in my travels from now on. It looks up to the task. Again, it is so spacious you might get lost in there. You might forget where you put what. The exterior looks rugged and like it can take some abuse e.g. dragging it, bumping against surfaces - all that abuse we dish out to backpacks subconsciously after we're past the allure of it being new. I like the zipped side pockets that hold the water bottle or umbrella very tight. It reduces the risk of losing stuff. It does not have hidden zippers for security unlike some of its competitors like the Sosson bag. I had ordered that one and it took forever to be dispatched I ended up cancelling the order and buying KROSER.

This is a pretty good bag! It’s huge, maybe abit too big and definitely bigger than I was expecting but it is a good bag.

The pros are it’s big so it fits everything in, the material is strong and is water resistant (I got caught in heavy rain for about 5-10minutes and my bag was dry in the inside, and semi dry on the outside because the water trickled off it), it’s has a lot of pockets: 3 main compartments a laptop compartment (fits my 15.6in laptop with plenty of space left over about 3 inches in height left over and 2 inches to the side), the main compartment is huge and has one large zipped compartment, a pocket for your tablet or Note pad and a pocket for your water bottle or to store a battery for the charging point (battery not included) and also has a large zipped pocket. The front compartment has loads of storage compartments it has a large zipped compartment and another open compartment and then a small mesh zipped compartment and little pockets, then two side zipped pockets and then a front zipped pocket I think in total it has 16 pockets.

The cons are it’s too big really, I can never find anything because I can’t remember what pocket I put it in to.

It’s a great bag but too big. I have added a video and loads of pictures so you get a feel of how big it actually is. The laptop is a 15.6in screen and the sloth notebook is A4

I am very happy with the product and the time it took to get to me, which was about a week.The backpack is very comfortable to carry, even with a heavy load. It has many useful pockets inside and the necessary couple on the outside. In its simplicity, it's also rather nice looking. It has a super nice zipper pocket for a laptop with extra, removable padding on the bottom. Zero doubts when considering the safety of such expensive electronics. I love it and I've gotten plenty of compliments on it.

The one downside of the product isn't really about the product itself, so it still gets a full 5 stars.I am quite the hobbit, coming at 5'1 (155ish cm), so the backpack can truly accentuate my baby face, and make me look like a preschooler.

All in all, I love this backpack and will take it with me everywhere until the straps fall off. (which doesn't seem to be soon)

The bag is great. Zips are high quality. Seams are nicely done and it has a ton of space. Lots of pockets and the side pockets have netting inside so you leave them open.

Only surprise was that the charging port has a resistor that limits the charge to 0.5amps (500mA). So half that of a standard iPhone charger. Good to keep your phone topped up but a real slow charge. I can only guess this is to stop a port that's exposed to weather from throwing out bolts of lightning.

I bought this after my old Laptop backpack broke. I spent a good deal of time looking at the options as I wanted something that was well made, big enough to fit a range of laptops in as well as an A4 notebook as well as all the kit I need when onsite at work and also had to look smart/understated.

This one fitted the bill. It is a nice simple design and is nicely constructed. it has useful internal pockets to hold pens, cables and portable drives and a decent sized main compartment. It has an external USB that you can plug a power bank into and there is a handy pocket inside to hold the power bank securely. This is handy as I am finding my phones just don't have the endurance they once had so often need a top up during the day.

The only negative I have is that this bag does not have a dedicated sunglases compartment. It's not somehwere I woudl put them as mine are prescription sunglasses but the compartment was always a handy place to kep my work ID as well as a secret stash of Sharpies!

Just got this. It appears to be well designed and made. I like the square shape it opens into, rather than the hanging shape most backpacks have.Small note, based on previous questions/answers ..There is a strip of cloth covered hard foam at the bottom. Its about 1cm thick, the width of the compartment, and on edge, so easy to miss. Turn it flat and press down and you'll find it will stay in place, certainly if your laptop is on it.

5.0 out of 5 starsFantastically well made 17" laptop back pack three thumbs up!

Size: 17.3 InchColor: A-charcoal Black-17.3"Verified Purchase

I don't often write reviews but this backpack for my large gaming laptop is great, the material quality is really really good just as good if not better than any of the ridiculously expensive brands - I travel a lot and get a few comments off fellow entertainers. If you want a backpack for a 17inch laptop plus the other ridiculous amount of compartments, don't hesitate! It's replaced my carry on case completely.

I've had several different backpacks, but this one is the one I keep coming back to. The compartments are well designed, with the computer "pocket" large enough to accommodate a range of different laptops. The largest compartment holds a fairly bulky winter jacket with no problem. Smaller compartments have pockets (some zipped, some not) that hold the tablet, a Kindle, my mobile phone, plus penciles / pens and other business / academic supplies.

The straps are easily adjustable so I can adapt them for tee-shirts or thick winter coats. The fabric folds over the zippers, so while it may not be totally waterproof in all weather, I've not had any issues with water getting in to the backpack.

Minor nuisance: I don't use build-in chargers, so that's just in the way - but it is minor.

I carry around a lot for my job, I work within the IT/Education so I need to carry around quite a bit of kit.

For the last few years I have been using a backpack made by Belkin, two of them infact. The first one the zip broke and the second one, you guessed it, the zip broke. They were both the same model of backpack but it suited my needs perfectly. When the second one broke I was just going to go ahead and buy a third until I found out Belkin had discontinued making those particular backpacks.

So the search for a new backpack began!

I knew I required a 17 inch laptop backpack to begin with as I sometimes carry around my own laptop which is quite big (more about that later). I also needed the same amount of space that the Belkin backpack offered.

Another requirement is that whatever backpack I chose had to have adequate water resistance as I would be carrying around various pieces of technology from time to time. The Belkin backpack was great at keeping water out, the outer material could potentially get wet due to good old English weather but it would never penetrate the inside of the backpack itself.

I am one of these people who scour reviews before making a purchase and I have to say, I was pretty impressed with the reviews for this backpack so I went ahead and ordered it.

The first thing you will notice about this backpack is the amount of space. That is the only good or bad thing about this backpack depending on how much space you actually need. I am finding that the space on offer is pretty excessive. Again, this could be good or bad and this is as close that I can get to criticising this backpack.

To get a better idea of how much space is in this bag I'll tell you what my typical contents are. Wallet, keys, full size coat, iPad, Kindle Paperwhite, sometimes a MacBook Air. I can also fit in a lunch box, precision screwdriver kit. It doesn't sound like a lot but all of this would hear enough fill up my old Belkin backpack but with this backpack this list of contents only fills up about half of the available space.

What I like most about the KROSER backpack is that when you have a lot of items inside it, it doesn't feel heavy. This is important for me because I commute to work.

The material itself does get wet in the rain. This was a worry for me at first but you find that there is a waterproof type material inside the backpack which somehow protects the contents. As mentioned earlier this was something that was very important in my choice of purchase and it just goes to show that previous reviews are reliable.

I mentioned earlier about my own laptop, I used to be able to fit this into my Belkin backpack and because it is a 17inch laptop I had to find a backpack that fits my laptop. Well, it doesn't. I'm not saying that you shouldn't get this backpack even if your laptop is 17inch and that's why you're planning to buy it. In my case, my laptop is a really weird shape and the corners just don't quite fit in.

Despite the last caveat, this backpack is definitely worth the price. You get what you pay for with backpacks so it is sometimes worth paying for something like this backpack, not too cheap but not too expensive but all in all you get a high quality product.

This is good - would be 5-star except the zips are made of soft metal and prove easy to bend and jam or come off. Furthermore, two of the zip pulls have fallen off. I have had to repair this several times within weeks of purchase.

Penny pinching in the zip materials will likely be the reason this bag stops being useful as there are only so many times you can take a pair of pliers to it to ben it back into shape before these will break - all else about it makes for a good school bag. How much would it have cost to have used better zips?

I would personally not buy this bag again until I saw the maker had realised this problem and made a "mark 2" version with say YKK branded zips. This is a sad recommendation - as there is a lot to like about this bag.

5.0 out of 5 starsYeah you’re late for work. But this bag looks like you have your life together.

Size: 17.3 InchColor: A-grey-17.3"Verified Purchase

I, like you have to go to work, and I do (sometimes) like to make an effort. Of course it caused a right stir in the office when I swished in (it felt like the first day of term in the 90s all over again - without the zigzag parting and impulse). It’s a nice grey and is actually comfortable to wear. Has a lot of compartments and I hope one day to find a lost lottery ticket or at least some gum in one of them. Buy it, purely to make the office know it all / has to have the latest thing, jealous.

Good day sack for the office, I have a surface pro and it fits snuggly. There are enough nooks and crannies for the bits and pieces you need to survive a day in the office and the battery pouch and USB port work well. It looks fairly smart and has good padding on the back so it’s comfotable for the walk to work.
